To all whom it may concern:

Be it known that I, CHARLES S. LocKwooo, a citizen of the United States,residing at 496 Clinton avenue, Newark, county of Essex, and State ofNew Jersey, have invented certain new and useful Improvements inRoller-Bearings with Sectional Rolls, fully described and represented inthe following specification and the accompanying drawings, forming apart of the same.

This invention relates to an improved construction for the rolls of aroller-bearing, by which rolls spirally grooved or wound in oppositedirections may be employed to facilitate the distribution of oil in thehearing, and without any tendency of the rolls to crowd toward eitherend of the hearing so as to wear upon the heads of the hearing or theheads of a cage movable therein.

Such tendency is avoided by means which operate independently of thecage to hold the roll-sections from moving apart from one another.

To prevent the sections of the roll fi'om working apart from one anotherwhen carrying a heavy load, a tie-bar is inserted through the bore ofthe roll and collars secured upon the tie-bar in contact with shouldersupon the ends of the roll; thus preventing the sections from separating,but permitting them to turn freely independent of one another whenrequired.

Such tie-bar is preferably formed with pintles at the ends, the tie-barbeing shouldered down to form such pintles, and at the same time to formshoulders to which the collars may be secured. Such pintles are adaptedto ilt loosely in holes in theheads of a roll-cage, and thus hold therolls in arallelism during their movement in the caring.

The collars may be verycheaply secured to the tie-bars adjacent to theend shoulders, by grooving the pintles next the shoulders and after thecollars are applied thereto pressing the metal of the collar inwardagainst the pintle and forcing it into the groove, which looks thecollar permanently thereon.

The invention will be understood by re erence to the annexed drawing, inwhich Figure 1 is an end-view of a roll-cage with one of the cage-headsremoved; and the collar in the nearer end of one ofthe rolls omitted.Fig. 2 is a section of the roll-cage on line 22 in plied to the rolls.In Fig. 2 the ends of the rolls are recessed to receive the collars.Fig. 3 is a side-view of one of such rolls removed from the cage; Fig. 4is an end-view of said roll; Fig. 5 is a perspective view of one sectionof said roll; Fig. 6 is a side-view of the tie-bar used in said roll;Fig. 7 'is a view of one end of the tie-bar enlarged with a collarlocked thereon; Fig. 8 shows a section similar to that in the lower partof Fig. 2 with the collars bearing upon the extreme ends of the roll;Fig. 9 is-a side-view of such a roll, and Fig. 10 is an end-view of'sucha roll.

a and a designate cage-heads of usual construction,-the heads a beingomitted in Fig. 1. b designates cross-ties having their ends secured tothe heads when the parts are all assembled. Each roll is shown dividedtransversely into sections 0 and 0', being formed of strands woundspirally in opposite directions with grooves or interspaces d betweenthe coils. the end of the roll is shown with recess e forming anvannularv shoulder e far enough within the end of the roll to receive acollar f. A tie-bar the roll in the lower part of Fig. 2, its ends beingshouldered down forming pintles h to fit rotatably in the holes 2' inthe cage-head.

The shoulders upon the tie-bar are at such distance apart that when thecollars f are secured upon the pintles the roll-sections c and 0' areheld snugly together but rotatable independently of one -another.

A very effective way of securing the collars next the shoulders upon thetie-bars is shown in Figs. 2, 6, and where the neck of the pintle isshown withan annular groove j, and a collar is shown applied to thepintle in cont-act with the shoulder upon the tie-bar, and the metal ofthe collar pressed inwa dly around the pintle, as indicated by thedepression liesuch pressure upon the metal crowding it into the annulargroove 9', as shown in Fig. 7, and locking the collar firmly to thedie-bar.

By forming the recesses e in the ends of the rolls, the collars can besunken therein and the healing-surface of the roll thus enabled toextend from one of the heads to the other in the cage.

The tie-bar and collars-can operate in precisely a similar manner it thecollars are Fig. l, with both heads t .In Figs. 2 to 5 inclusive, I
